makefs: Make it possible to silence warnings about duplicate paths

When generating a VM image from an installworld mtree manifest, makefs
spits out several thousand warnings about duplicate paths in the
manifest. These are harmless and have been around for a long time (see
the phabricator revision for some more details), so let's at least have
a way to make makefs quieter.

the optstring or if a flag is missing its option argument. We can
handle this case with the "default" failure case with no loss of

makefs: Add ZFS support

This allows one to take a staged directory tree and create a file
consisting of a ZFS pool with one or more datasets that contain the
contents of the directory tree. This is useful for creating virtual
machine images without using the kernel to create a pool; "zpool create"
requires root privileges and currently is not permitted in jails.
makefs -t zfs also provides reproducible images by using a fixed seed
for pseudo-random number generation, used for generating GUIDs and hash
salts. makefs -t zfs requires relatively little by way of machine
resources.

The "zpool_reguid" rc.conf setting can be used to ask a FreeBSD guest to
generate a unique pool GUID upon first boot.

A small number of pool and dataset properties are supported. The pool
is backed by a single disk vdev. Data is always checksummed using
Fletcher-4, no redundant copies are made, and no compression is used.
The manual page documents supported pool and filesystem properties.

The implementation uses a few pieces of ZFS support from with the boot
loader, especially definitions for various on-disk structures, but is
otherwise standalone and in particular doesn't depend on OpenZFS.

This feature should be treated as experimental for now, i.e., important
data shouldn't be trusted to a makefs-created pool, and the command-line
interface is subject to change.

I would prefer to avoid the duplication, but reluctance to doing so was
expressed in a previous review (D11197); for now copy the files and
revisit in the future.

various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.
